The easter egg area is just a secret area, like in MM series. you need several items in order to proceed to this area.
On the right side of the pic are the 2002 gold, the four ropes, the 5 ales and the pyramid you need for getting out. You need the silver armour, too.
Everything colliding with this: more gold, other ale should stay out of the inventory - just drop it where you have your other tellie (maybe in your home base? Anything else may stay in your inventory.
After stepping on the teleporter, you get to the area in this pic. You click on the hatches there (white crosses) to open them, then drag and drop your ropes over them and descend.
Now you're in the prison area, opening the doors via levers and using lockpick, you eventually come to Sven - and then descend into the cellar with the bug area. You fight the bugs there, come up, talk again with him and have the armour.

2002 gp = the release year of Div
beer = hm, cause the company is in Belgium and Belgians like beer?
ropes = so all those ropes in the game finally found a use?
pyramid = progr. error, the teleporter in this area was supposed to work...
armour = well, you need something to upgrade, don't you?
