Sebastian and Collins could be seen chained to the wall in a dark room without a trace of light. It was as if the light had abandoned it leaving it in total and complete darkness.
The wounds on their bodies had not healed, they were not healing as they should have after the battle may be due to over-exhaustion or something to them by order of the vampire lord and they have been severely beaten for the loss of so many comrades.
While Sebastian was sent to the Shadow moon pack, Collins was sent to The Jewel pack where he also lost many vampires and werewolves. They were both the leaders of the ambush in their respective packs.
After their return, and the news of their defeat was reported to the lord, he had them beaten and locked up in the darkroom without the slaughter hinting of light penetrating in. At first, even with their sight as shifters, they could not anything. It was after some time that their eyesight adjusted to the darkness and they could now see each other.
