It's over half a mile from the juggernaut to the doggedens so you can't make out specifics over there. The bards seem to be mostly keeping the people calm in the courtyards.
If you want to head back to the wizards you could land and run faster than you can fly. Rubius is flying back now.
Ok, then Parker will land and run over to the Wizards and tell them what is happening and ask them to keep that things attention if they can or help Ari if possible. He'll tell them about the barrier he ran into/couldn't bring himself to cross and see if there is anything they can do about it.
Then Parker will run to the nearest group of Bards/students and tells them to spread the word to have half of them move closer to and spread out along the walls so that the defenders will be able to hear them, (in groups or individually whatever works for them). Any of them (the Bards) that have spells that enhance and/or project their voice are strongly encouraged to do so as well as anything else they can do to bolster the defenders. Parker will tell the gathered bards that it is time to do their part in this battle. Parker will take a group of 4 or 5 of the most talented in the group and tell the rest that they are to join in with whatever song Parkers main group is singing. The effect will be (and Parker will use these words in his speech to the others) that the walls will reverberate with our unified voice, reminding the defenders what they fight for, lending them strength. Our enemies will hear the depth of our resolve and know they can not win.
Once they have spread out enough, Parker will tell the group of bards he pulled aside for this group to play inspirational songs that just about everyone (the other bards/students) would know, but to start with one he wrote, and then play it again at regular intervals throughout the battle (because Parker is, if nothing else, an attention whore).
Here is the song (my apologies (again) to Daughtry)
it's a world full of heartbreak fly-bys
we've seen our fair share of hard nights
looked right into the face of a goodbye
while we walked on the edge of the dark side
after all this time, yeah
we're not gonna fall now
we're not gonna bleed out
never gonna break down
no, whoa
when it's these Castle walls they try to cave in
and the ground underneath starts shaking
it's the hope in your eyes that we cling to
and i hope to gods it never leaves you
after all this time, yeah
we're not gonna fall now
we're not gonna bleed out
never gonna break down
no, whoa
[x2]
even when they come for us
everything can turn to dust
you and i are never going down
the spells and monst'rs they send at us
with Giant, Hunter, and Zigaraut
we will never give it up
oh, oh
we're not gonna fall now
we're not gonna bleed out
never gonna break down
no, whoa
[x3]
This will, hopefully, have the added effect of calming/rallying the people as well
