I was wondering if anybody has any clarification on whether or not you can take multiple strongholds in one turn.

As in can you spend gold to get one stronghold then use military power from other cards in your hand to take another all in one turn?

If an instant event attacks me with a power of twelve for example and after i put down army units from my hand and resolve effects i have a power of 9, i know my home realm takes 3 damage but do my army units get discarded or destroyed and returned to their place of origin?

furthermore am i just out that many cards for the whole next round until the next draw phase or is there some mechanic i didn't read that lets me draw more for my next turn?

Wounded and destroyed units go back into your barrack while your other units go into your discard pile. I see no rule saying that you can only acquire one stronghold per round, so I guess that you can acquire as much stronghold as you want if you have the required resources at your disposal.

Based on your example, the way I have been playing (and interpreting the rules), your home realm would take the three points of damage. Unless you have to remove units because of the attrition roll, or unless the instant specifically says so (apply one wound to each unit, etc.), your unit cards are returned to the discard pile for use in later turns. Anyone playing this differently?

You draw back up to 5 cards after resolving an event (end of the "event phase") as well as at the end of EVERY player's turn. Thus you are never stuck without cards.
