So I posted and the event with the Crag Beast is not really meant to be responded to right away, but you can respond to it if you want. Especially if you're Riven or Sona lol. But yeah, eventually, the rest of the group will gather there to help fight off the beast and help keep the people safe. More than likely, the town guard will try to meet with the creature to intercept it before it reaches Janelle, but they might get barreled over.
