What do the other 3 sides look like? What does that top face represent? If they all represent numbers, then the only thing I'd be paying attention to are the pips. The strange font would be really hard to recognize if they're not upright relative to a player.
The bottom would have the same symbol as the top, which is the Victory symbol in the game. These dice work like the dice in Merchants & Marauders, with two sides for Victory. The other two sides you don't see would be the 2 and 4, in the alien font with 2 and 4 pips respectively. I put the pips on them so one can easily distinguish the number rolled, as the alien font is primarily there to give it a thematic look.
