Pretty sure it's confirmed that it is an LCG

While rummaging through a desk, you find a document that appears to explain how creatures are able to travel between worlds. Strangely, as you read each word it seems to disappear before your very eyes until the page itself vanishes when you reach the end. Make a Lore check and gain one clue for each success. Then, lose 1 Sanity.
