Found you. I was looking around for single planet empires for ages, you're a lot further than I thought you would be for a "couple" of days - your home planet says 11 days (I'm presuming home planets grow by 1 level a day).
Yeah, I started, sent out a bunch of arcs, and then forgot about the game for a week and a half.
Your nearest neighbour is Fodder. If you go out two rings and then counter clockwise four segments, he's the yellow one. Near him is Silverfire (KingDante, orange) and Squishymaster (grey-blue).
If you go inwards 2 rings and clockwise 7 segments you'll find Adriddae (vistuvis, orange).
Cool.
