My gameworld has a hmmmmm archetype? That sometimes were called justiciars originally like police back in the ancient times but many of them became more like personal guards in modern times. Green Knights were one such group who I sort of hedged as being like druid/fighters when it was 1e days. But the Warden in 4e was associated with the Nature magic / sort of Druidic branch it fit rather well.Mage Hand Press has a really nice Warden class that's probably the closest I've seen to fitting the 4e defender paradigm; unfortunately it's still limited to Patreon subscribers.
Is this like those Wardens?
