The innermost, smallest, fastest... hottest!
Striker holds a few records: it is the closest planet to the PE31 star, it is the smallest and the fastest one in the star system. Such conditions create an environment with a extreme temperatures where lakes of metallic, orange-glowing lava radiate out the planet's heat deposits. Harsh conditions is the understatement when speaking of Striker. Still... A fly-by (or two) is a must for every respectable space explorer.
