Forum:Ultimate Offering and Monarchs

Scenario
My opponent declares an attack with Cyber Dragon. I have Breaker the Magical Warrior on the field and Caius the Shadow Monarch in my hand.
 * Chain Link 1: Mirror Force
 * Chain Link 2: Draining Shield
 * Chain Link 3: Ultimate Offering

My opponent does not add any links to the chain.

Resolves

 * Chain Link 3:Ultimate Offering summons Caius the Shadow Monarch with Breaker the Magical Warrior as tribute.
 * Chain Link 2:Draining Shield resolves normally.
 * Chain Link 1:Mirror Force resolves, since a declaration of attack occured, although the attack was negated.

Question

 * My question is, does Caius the Shadow Monarch's effect occur "'mid-chain"'? That is to say, after Chain Link 3 resolves and before Chain Link 2, since Caius's effect is mandatory?
 * Or, does Caius's effect start a new chain?
 * If a new chain is started, my opponent can chain like normal? (i.e. Divine Wrath)
 * In both cases, would Bottomless Trap Hole Miss the Timing? Since the last thing to happen in the first chain was Mirror Force
 * In both cases, if Sangan was tributed for Caius, would Caius's effect be chained to Sangan's?
