Mafia 92. Void Lord.

Here is an example of how you can find a connection to Game of Thrones without being a fan of the series.

The only resource I found that clearly describes this connection (at that time, the level of evidence was the same as "she was killed by the one who was with Margarita") describes the manticore as an insect with a scorpion's stinger. It has nothing to do with a human and a lion.
