that's more of an obligation to armadyl than a personal wish, seren left many scars behind, armadyl want to reconnect with the people of abbinah not as a leader but a compannion, that's why I drew armadyl not at the front of the group.
In my personal headcanon you're correct in your interpretation. He's planning on heading there, but it's not like there isn't stuff to do on Abbinah first. Certainly he wants to connect with his people and his roots again.
Before he can help another people, he has to first learn to help his own.
