So Fin put his hand out, his fingers shaking a bit, and touched that cold door with all the weird marks on it.
The second he did, it was like, whoa, this super cold feeling, way worse than ice, shot right up his arm and slammed into his chest. That Mark of Dominance thing he had just flared up like crazy, all red and black, and it hurt like hell. For a second, everything went white, and he heard this loud roaring sound, like a giant storm was happening right inside his head. He could also feel his domain, his special place, starting to actually tear, which was a really bad feeling.
'No, man, stop, this is too much,' a part of his brain was yelling.
But another part of him, a colder part that felt super guilty about Mara and just really didn't want to fail her, pushed back hard. He bit his lip so hard it started to bleed, and then he just pulled. Not with his actual muscles, but with, like, all his willpower and whatever was left of his messed-up powers.
