Eren deliberately avoided public appearances after the completion of the Lazarus Project, even within Ravendale.
His interactions were limited to select Rankers, half-bloods, and monsters, as he focused on advancing in his Ranking Path and digesting the insights he had gained. Public attention would have only diverted him from his crucial pursuits.
The public perception of Eren as the most evil entity in Arsalan and Katiyal or as a savior in Shiragna and Velen didn't bother him. His motives weren't driven by a desire to spite or save any particular group; they were rooted in serving his own interests.
Consequently, he felt no need to explain the reason behind the Lazarus Project and his circumstances.
Despite this, Eren allowed his organization, particularly the White Raven Guild's mass media arm, to issue statements on his behalf. The guild actively made often absurd claims to rationalize Eren's actions.
