Well..everybody knows the most of marauders make PvP everywhere but..maros make pvp also in their camp and they don't have any respawn point there..if a maro was engaged with another one and he dies he cannot respawn in the camp because the teleport doesn't work when your pvp tag is red (when you were in engaged).

'On Ryzom, PvP is at all times consentual. Activating your PvP tag, entering a PvP zone or engaging in an outpost battle implies that you accept the consequences. To put it another way, if you don't want to take part in PvP action, then do not activate your tag or go into PvP zones.' - Code of Conduct
