Rosemary Stalk


First we were shown a train path with the Lucian, Tomas, Ekat, and Janus crest. Then, we were outside of the entrance of NY subway. The screen dragged us past, through the pipes, into a tunnel with the passing train. We dodged it by hiding below the moving train. Then we saw the soil crack and a rosemary plant grow. We were dragged down again and the word 'ROSEMARY' appeared with the crest.
