I would say solar systems are near and dear to all EVE players.
I would use the historic systems of EVE to name your new rooms.
Jita and Amarr could be a large conference rooms, Developers could contemplate the future of EVE in Ruoa, GM’s could assist players all over New Eden from Thera, the Security Team could dispense justice from Yulai, Artist’s could sit in the glory of Caroline’s Star and though you said you only wanted named systems in honor of EVE’s world record you should most definitely set a room to be the legendary B-R.
Food for thought, though you should have a nice peaceful room so you can be left alone in Cat.
Those subtle hints before the meeting even begins Although for ship names The t2 amarr line up have some pretty scary names for meeting rooms: Confessor, Retribution, Damnation, Vengeance xD
The sheer depth of the history of each region speaks for itself. The weight of all the conquests, battles and wars would inspire you.
Project kick off meetings in Genesis
Quiet reflective meetings in Placid
Design meetings in The Forge
Build meetings in Delve
And the meetings no-one wants to attend, in Cloud Ring
