Was playing my first game, solo and had only Romans. Auedui were first and diced to play the druid event. They must select 1-3 Gallic factions to perform limited command and special ability.
I have to questions
1. How do they decide how many and which of the Gallic factions they will choose?
Per 8.2.3 bullet 2:
"When there is a choice of who gets Event benefits (such as free
actions, Capabilities, Resources, or pieces), Non-players select
So they choose Aedui only.
2. When they make a limited command (it is cause the event asks for it) they choose only one origin or one target region for the command?
Only 1 Region (which may be an origin for March for several others , for example) for an Event-directed Limited Command, per 8.1.2 and Note:
"When a 2nd Eligible Non-Player by the Sequence of Play is to execute a Limited Command (2.3.4-.5), the Non-player instead receives a full Command plus a Special Ability option. NOTE: A Limited Command by Event, such as Druids, remains Limited (5.1.1)."
