An apt question from a Druid has spawned one small modification to HELP
PKCAUSE Section 9. Instead of "...refuses to leave after being asked to
(or is clearly not welcome)...", it now reads "...refuses to leave after
being asked to (or, in the case of group interest property, is clearly
not welcome)...". As before, you still do need to ask a trespasser in
your grove to leave before attacking, even if they are on your enemies
list or otherwise clearly not welcome in your eyes.

The reason for the differentiation is that anyone can walk into a grove
by mistake, en route to somewhere else, whereas it is difficult for
anyone to simply wander into group interest property.

Penned by my hand on the 4th of Lupar, in the year 386 AF.
