Erim is much stronger than Gades and Amon, and is frequently depicted as being close in strength to Daos. She tends to rely mostly on magic in battle, with some attacks that can kill instantly. The first game depicted her wielding a trident in one hand, but in Lufia II: Rise of the Sinistrals she is depicted wielding a sword and a shield. In Lufia: The Legend Returns, she uses a naginata and shield.
Erim firstly appears as the third Sinistral boss battle at Doom Island. She is notable for using strong electricity-based magic, which is an ironic contrast to other Sinistrals' weakness toward thunder. In addition, she's the only Sinistral who doesn't have an elemental weakness. Erim doesn't appear as a boss during the main game.
It is revealed that she was actually Lufia herself, though she was not able to remember her past because she suffered from amnesia. Eventually, the other Sinistrals were able to recover her memory, but she later rebelled against her brothers and defeated them along with the hero and his friends at the cost of permanently losing all of her memories and her ability to use magic.
Erim appears to Maxim as Iris, a mysterious sorceress who can divine the future. It is upon her suggestion that Maxim seeks out the disaster visiting the world from the red comet and later the Sinistrals. Iris' role is to appear from time to time to offer advice and test Maxim's strength; however, she "disappears" without giving complete instructions and thus never tells the party the full truth.
Late in the game, it is revealed that Erim began Maxim's quest to decide which race was powerful enough to rule the planet. Iris has a tendency to offer too much help to Maxim. He was fated to die after Gades' first death, yet Iris teleported Maxim to Parcelyte instead. Additionally, when the death of Maxim's son Jeros would cement the foundations of the Sinistrals' rule, she betrayed the Sinistral minion Idura by saving Jeros. Finally, when Maxim is trapped in the falling Fortress, Erim appears as Iris and allows access to the Island's Power Stones, which alter the Fortress' path and save Parcelyte when they are destroyed. It is suggested that Erim develops her compassion as a side effect of being Iris.
In Battle Statistics Edit
|Special Attacks||Devastation Wave, Dark Fry, Eerie Light|
Erim is actually Seena, one of the main characters and Wain's target of affection. She disguised herself so she could find and train friends strong enough to kill her, as she could no longer bear the existence of being a Sinistral.
Erim appears to Maxim and Gades disguised as Iris, a mysterious sorceress who can divine the future. Gades decide to stop fighting and Iris decide to journey with Maxim and professor Lexis. From there on out, Iris plays a major role throughout the game.
After completing the trials in the three towers, Iris reveals that she is Erim right in front of the heroes and Daos. Erim reveals that she journeyed with the heroes to have them gain trust from everyone so that they can crush their faith once they defeat the heroes. Iris also reveals that as a Sinistral, she was made to kill the heroes. Rather than battle on top of the towers, Iris and Daos welcome them to Doom Island to fight them there.
On Doom Island, Maxim urges Iris to stop because they don't want to fight her. Iris says it is fate that they do battle, so she teleports them to her battlefield. The heroes have no way of touching her at all nor do they wish to fight her despite Iris going all-out assault. After a certain time lapses, Iris stops the fight and demands why they won't fight her. A wounded Maxim believes that Iris is still helping her somehow before passing to near-death, but not before convincing Iris as a friend who traveled together. Iris, showing compassion for the first time, resurrects Maxim. At this time, Iris is in emotional conflict with her role as a Sinistral versus her friendship travels with the heroes. Suddenly, time stops and Daos stabs her in the back, killing her for betraying her role. Her death has caused the heroes to be angry at Daos for killing his own kind, especially after forgiving Erim of her actions. Daos' actions have cost him the Dual Blade to reside with Maxim instead.
When Daos is defeated and Doom Island is being sent to collide with Parcelyte, Iris somehow reappears in front of Maxim and Selan; it is unknown how she revived. She hints that the only way to change the course is to use their energy waves with the Dual Blade and break the dark crystals within the core.
On the first ending, Arek asks Iris of her observation of humans. She mentions that they are a young but strong race, willing to help and love each other in need. Showing compassion towards humans in front of Arek and her indirect feelings towards Maxim, Arek presents her with the Dual Blade and knows that the journey isn't over for either humans nor gods. The reason why Arek showed Iris the Dual Blade was due to its ability to manipulate time and possibly Arek not getting a fully truthful response from Iris. The Dual Blade reverts time to go backwards, using Iris' energy waves. Iris demands the Dual Blade why, though no answer was revealed but leads to New Game+.
During New Game+, right when Maxim and Selan were about to break the final dark crystal to prevent it from colliding into Parcelyte, it is revealed that Erim has changed the course of time by interfering with their mission. Erim claims that Iris is no more and has put Maxim into an ultimatum. Maxim decides to finally fight Iris, knowing that by not doing so, Doom Island will collide with Parcelyte and kill everyone there. The Dual Blade is transforming to its true form, showing that Maxim is at his full potential. Both Iris and Maxim fight 1-on-1. After Maxim defeats Iris, it is indirectly revealed that Iris used the Doom Blade's power from the previous timeline (not New Game+) to change the course of history. Rather than Maxim and Selan using their energy waves and sacrifice their lives to save Parcelyte, Iris forced Maxim to fight to their fullest in order to have the much stronger energy waves during the battle change the course instead. Right before dying, Erim teleports Maxim and Selan back to Parcelyte to finally visit their family. Erim's previously torn conflict concludes that she sided with human friendship over Sinistral godhood.
On the altered New Game+ ending, Arek shows satisfaction that Erim was the first Sinistral or God to express attachment to humans and to willingly sacrifice herself for Maxim and humans in general respectively. During the game's alternate ending, he vows that Erim's sacrifice will not be in vain. He mentions that the Dual Blade wants an endless adventure towards the future. It is hinted that the Dual Blade is even more powerful than Arek himself. His fate is left unknown.
Erim plays a major role in the series, as she usually appears to be the love interest to those of the Maxim bloodline. As long as Erim lives, the other Sinistrals are able to resurrect themselves. At the end of The Legend Returns, Erim's goddess side is destroyed (apparently destroying the Sinistrals for good), but her human side remains, allowing her to live as a human with Wain.
Strangely enough, her alter ego Iris appears in the same game as the final boss of the Ancient Cave. Upon reaching her, she will praise the hero's bravery for coming this far and thus will use the full extent of her powers on Wain and his group. After being defeated, she states that the group could be powerful enough to take on Lord Alekdias (Arek), but quickly dismisses this thought, as she wouldn't believe it herself.
