Circe had decided that the new arrivals needed to be kept up to date on a few things. She had discovered that some had gaps in knowledge that would confuse many mundies as to why they didn't know it. Thus the beneficence and nobility of Summer's Queen would aid them correct this while providing for their other needs as well.
Or Circe had decided this was a great excuse to have her place's first party with the big screen and sound system.
Messages, word of mouth, telephone, email, and directly walking up to and inviting had been her methods of choice for ensuring that the folks would show up. Or in John 's case it was the simple fact that he also lived here. Titania had been the first invited as she was the "inspiration for this gather oh ho ho ho" to quote Circe.
Blink and Tiphon were invited because Circe wanted the Summers comfortable enough to approach her home when they needed to. Rounding out the invitations was Penance for slightly less altruistic reasons. Circe still thought her blue and Penance's red was a great contrast so she was not giving up on Penance eventually becoming a Summer.
ooc: just a little social thread at a private location inviting a large portion of Circe's IC social circle. No plot, no plans, just antics as they prepare for movie night. PS Yes the misspelling of the thread title was intentional
