Basically his lore is that he’s Asgore’s half brother!! (don’t ask me about their parents lore i haven’t thought of it yet ^^;)
But he’s kind of like almost like a park ranger for Snowdin, he lives in the one little house you can see in the distance in Gyftrot’s area!! And in Deltarune he’s the gardener for the graveyard!! He’s the literal “black sheep” of the family and mostly keeps to himself. He moved to Snowdin after the whole Asgore and Toriel breakup since he felt useless just staying in the capitol.
Honestly I need more ideas for character traits for him
