Because sandbox games really kinda rely on random encounters, I figure there needs to be one for space travel. So here it is...
Roll 1d100
01-50 = No Encounter
51-52 = Pirate Ambush
53-54 = Mynock Swarm
55-56 = Starship Crossjump
57-58 = Cosmic Rays
59-60 = Gravity Storm
61-62 = Solar Flare
63-64 = Jammer Leechs
65-66 = Meteor Swarm
67-68 = Sluk Bed
69-70 = Mortiss Colony
71-72 = Asteroid Spider
73-74 = Murderoid
75-76 = Astereater
77-78 = Mercurial Slime
79-80 = Q'nidar Pack
81-82 = Blazozoid
83 = Wormhole
84 = Silatic
85 = Witchlight Marauder (space)
86 = Zwarth (spirit warrior)
87 = Clockwork horror
88 = Gonn
89 = Focoid
90 = Rogue Moon
91 = Gravislayer
92 = Constellate
93 = Gammaroid
94 = Rogue Star
95 = Great Dreamer
96 = Esthetic
97 = Monitor
98 = Moon Dragon
99 = Sun Dragon
100 = Stellar Dragon
A few are pretty obvious and I can detail later, but a few are kinda vague an unfamiliar.
- A Mynock Swarm is a swarm of mynocks, and will almost certainly end in an infestation on the ship, slowing jump speeds dynamically.
- A starship crossjump is the rare event when two ships jump path intersects. It causes both ships to drop into normal space more or less face to face. I'll make a random table for the nature of the ship.
- Cosmic Rays is a fancy way of saying "lots and lots of radiation". The radiation is high enough it can overwhelm the ships shields causing damage to the ship or the crew or both.
- Gravity Storm is a area of space where gravity is...unstable. It causes ships to drop into normal space and plotting a jump out is +2 to whatever the difficulty normally is. It can also cause damage to the ship as gravity changes erratically.
- Jammer Leechs are magical space barnacles. They damage the ship and generally suck. When this result occurs, the ship arrives on target, but into an invisible spore cloud. Within month the infestation takes hold and the ship begins to take damage.
- Sluk is space seaweed. It is nearly invisible in open space and can mire a starship.
- Mortiss is a form of magical space coral. It can, in time, turn a ship into an asteroid of hard clay.
- Rogue Star is a star thrown from the galactic center at tremendous speed. Getting close to one will cause a ship to come out of jump space and potentially damaging the ship.
