The Celestials have an axe to grind...
Exitar's pissed off at the no-name Celestials and their pathetic performance against a mere enchanted axe, he order The Celestials to go salvage some shred of their once pristine and shining dignity, from the Asgardian rabble.
ALL of Asgard, Thor, Loki, Odin and all his toys (Destroyer armour etc), are ready for The onslaught. They've had days to prepare (Celestials are never ones for swift action).
The Celestials attack as follows:
1) A random teapot headed Celestial turns up on Sunday.
2) A minor named Celestial turns up to aid his colleague (if he is still alive) on Monday.
3) Two more kitchen-wear headed Celestials of no name turn up on Tuesday, to carry the fight against Asgard.
4) Exitar's fury at the continued resistance proves too much and he joins the fight on Wednesday.
How long can Asgard hold out, will they see it to Odin's day? Will they see Thor's day?
