Liam is well liked everywhere in Neverearth not because of his achievements but in spite of it.
Liam is perfect, it is all he knows how to be, and if there is despair behind it that is his business. Liam notices that his kindness intimidates some of his classmates, so he responds, moulding himself automatically to present the type of perfection they prefer. He modulates his speeches and actions accordingly, and after a while they forget that his eagerness to throw himself in the path of danger used to frighten them, that his curiosity had once been the talk of the school.
He is just like them now, if not always a little above, and he feels himself slipping into the role with despair. It is nothing, really, just as his life is nothing.
He is still as capable as he ever was, spotting the tiniest of inconsistencies and following them, leaping across the landscape of suicidal impulse, but he slows his thoughts, picks his words with meticulous care and is careful in how he presents himself. Hard work, devotion and dedication, not the fact that he simply is willing to die, is the reason he rises above them.
Liam Mirth will go far, they say, and Liam knows it also and does not care. Liam knows that if he just has the right tools he could leave this world, never mind being the greatest wizard, and all his achievements mean nothing with this knowledge.
He knows there has to be a way out, that there must be something else to strive for, but he gave up a long time ago, perhaps even before he fell into Neverearth — what does it matter? He might be broken inside but his veneer is perfect.
