|Quest NPC?||Ghosts Ahoy|
|Examine|| This Ghost looks quite Rebellious.|
Gravingas is featured in the quest Ghosts Ahoy, is also a ghost protestor, protesting against Necrovarus and how he has affected Port Phasmatys. If you aren't wearing an Amulet of Ghostspeak, he will only speak in Ghostspeak.
- Gravingas used to speak on the overworld (not the chatbox) in English instead of ghost, even if the player was not wearing an Amulet of Ghostspeak. This has since been fixed so that he now speaks in ghost in the chatbox and the overworld. To players with a high prayer, he begins to tell the story of how he came to be the crier of the port, but eventually "woo's away".
- Some of the quotes that Gravingas says are excerpts from speeches given by Martin Luther King Jr. such as "We shall overcome."
- If you equip or unequip an amulet of ghostspeak while near him, he will switch to face the opposite direction.
