He's in the Waking Sands ever since ARR! The Miqo'te Tia friend of his has more to say about him in a ARR than Arenvald does himself.
There's some speculation, that just as Greystone for Ishardian, Lentinus may be the bastard name for Garlean offsprings - maybe even for half-Garleans in specific. Given Arenvald got cast out by his mother, and nothing implies his father cared for him, it might be the case. Seeming the lorebook does refer to him like that. No idea if he uses the name himself. Think he just refers to him as Arenvald.
But take that with a grain of salt at this point. It's hardly confirmed and people are just speculating.
Anyhow, as far as we know, these children appear to be shunned by both sides. I can't imagine the Empire, being as proud of their racial superiority, likes seeing their 'pure' bloodlines diluted. Next to that Arvenvald was made to live like a bandit back in Gyr Abania. So it seemed no one really wanted to associate with him. Because as far as we know, Ala Mhigan children get brainwashed for the Empire, but he seemed to have 'escaped' that. Probably due to his heritage.
