Young Slender explains to Trollhunters gang
Jim: So you said you were a Slender right?
Jim: What exactly is a Slender?
" Like I said before we are beings of the forest... I guess the easiest way to think of us is like the Fae creatures in English folklore. We are a branch of those ancient creatures most humans refer to as fairies. "
Toby: So like can you grant wishes!
"* you burst out laughing at his childish assumption* No. I can't grant wishes, I'm not a genie and neither are the Fae. Your question comes from a very Hollywood representation of the creatures if I'm honest your lucky I'm not my father or I would have been very insulted."
Toby: Awe!* he looks down sad* Sorry.
"There's nothing to apologize for I know you meant well by it."
Claire: So are there a lot of you that live in Arcadia's forest?
"No, I am the only one that lives here. Our kind is very territorial and I am old enough to claim an area as my own. My culture is strange when it comes to our habits. We like having big families, but don't like being around a lot of other Slenders that are not of blood. We have laws that prohibit the trespassing of one Slender on another territory. Come to think about it, I'm pretty sure a breach of territorial law was how my Father and mother wond up togeather. In honesty, the Slender culture is just a bunch of rules and customs. But that's a Story for another time."
