Reading through this thread from the beginning, I was reminded of the picture from the Fletcher Dawson site (I know there are only five constellation animals, but bear with me ).
In the picture we have two birds, a deer, a rabbit, and either a fox or a wolf.
In previous discussion on this thread:
If it's a fox, Balimora; if it's a wolf, Ebenguard.
Birds: Gossmere, Thornmouth, Ebenguard if the other's a fox.
Deer: Weatherwatch? (OracleSage mentioned elk at one point), Balimora if the other's a wolf (someone mentioned stags and nature).
Rabbit: in the poem, Flinterforge seems to be represented by the mouse, and a rabbit doesn't seem too far off from a mouse to me.
Probably reading too far into nothing, but on the off chance it's kind of something...?
There was also talk of Thornmouth being an octopus, and with their being left out of the code to get into the time-traveling email system, maybe it was supposed to be a super-obscure clue to that...
