These four Bākiraka are the personal bodyguards of Silat.
Each of these four men have knots on their knuckles and mysterious markings on their foreheads. Their bodies are muscular and their skin colour is brown, like all Kushan. The clothes they wear are small and light, so they won't be in the way, during battles.
Their personality can be said that they are very respectful towards Silat. They call him "young prince", which shows that they are older than their lord. So far, it wasn't shown that they talk to someone else then Silat. They also do whatever he orders them to do, even if it is something dangerous like attacking Griffith. The Tapasa also knew Rakshas, probably before he was exiled.
