SCP-354 is a pool of red liquid discovered in northern Canada. The liquid is of a consistency similar to that of human blood (hence the colloquial name Blood Pond) but is not of a biological nature. Periodically, entities emerge from the pool and attempt to escape from the enclosure. Thus far, nearly all creatures emerging from SCP-354 have been extremely hostile and highly dangerous. The setting is in a winter site created by the SCP Foundation. The lake mutates sometimes.
