FOR DETAILED DESCRIPTION OF THIS ARENA READ THE "DETAILS" SECTION BELOW!
okay so i've asked
if hel gets her own arena since he wants to return to the afl3 arena system and guess what? we're all going to make a trip to space in afl5
basically this is a very big room inside hels spaceship with a special holographic function.
(NOTE: this has NOTHING in common with the star trek holodeck where you can materialize crap out of thin air and stuff like that, so keep that in mind!)
the function of that room is similar to a CIC (combat information center) on a battleship, only much more sophisticated. instead of using small maps and radar and such, people can see the actual space around them and any points of interest such as enemies, allies, anomalies in space, etc will be displayed directly at their "actual" position.
it is also possible to show holograms of other people and talk to them, but only if they are on their own ships CIC.
so this whole thing is the extreme version of the augmented reality technology which we all know already from many other media.
although fighters won't be able to use the holograms to materialize things, they can however use the holographic functions to distract their enemy (for examply by placing a dozen map markers around his head or something like that).
although you can choose basically any space-themed background, you cannot change the background it shows (because the CIC is only able to generate the background of it's current position).
and now a final word of advise: although hel's ship is very durable, it is entirely possible to rip holes into the walls of the ship with enough force, which would lead to sudden and total loss of pressure and therefore an unwanted and possibly everlasting and definitely deadly trip to space (at least for any character that needs air to survive), so watch your actions!
