Alchemy 101

The second island has a central tower with an observatory at the top. After a long climb you reach the observatory and encounter an unexpected sight. Metal goblets are strewn about and a broken furnace sits in the center of the room. On one side is a shelf of half-shattered urns filled with odd ingredients. On the other side is what looks to be a schedule.

“Why would the Knights Templar place a laboratory in an observatory?” Drake wonders.

“I don't know Nate.....This all looks a little hinky,” Sully says.

“Hinky?”

You examine the schedule on the wall.
