Daeros is a powerful elf hailing from the cruel kingdom of Mor'althir, which does not take kindly to any non-elf species. Despite this and his stoic personality, he has willingly offered to protect you from the dangers of the forest for ambiguous reasons. He is a skilled user of the bow and arrow and has impeccable aim. He was a well-respected elf within his kingdom up until he escaped into the forest, just like you had. Perhaps this is why he takes a liking to you.
