An Lad - True identity? (SPOILERS)

[Puksi]

Do they ever explain the "terrible, grating voice"?

[Crushnight]

Gotta love the unbelievable coincidence that had to happen for An Lad's 'birth', child's soul being reincarnated as we kill and absorb the Lightwarden, though does beg the question would a primal dispersing also cause a pixie's 'birth' to give it a split memory as well?

Also An Lad is not the previous King Titania reincarnated they have however obtained some of their memories and desires creating the twin dreams An Lad suffers from, that come from both the unique child's soul and the previous King Titania's aether being dispersed. Really is just bad timing, kinda sad we save the region but condemn children to suffer nightmares that would've eventually claimed them had we not intervened.

There are five doors in Lyhe Mheg, which would correlate to each area of Norvrandt (minus the Tempest which is presumably tied in with Kholusia).

In light of that, I would posit that the last door is Il Mheg's and the voice speaking to An Lad is perhaps their nightmare.
