Brimstone is a five-part mission chain that begins as a search for a lost Independent ship, the Brimstone, and pulls you into a standoff between the Tholians and the Breen. All parts are recommended for level 42, and warp to complete stays between 64 and 70. The chain starts by finding the Enterprise in Hyland. Most rewards are Dilithium, Tritanium and refined resources, and the finale pays 2 Worf shards. Part 4 asks you to side with the Tholians or the Breen.

Tips for completing Brimstone
The fights in this chain are all listed between about 4.1 and 4.3 million strength, but they cluster. Part 4 has three in Zosam in a row, counting the escape you defend, so repair before you arrive.
The only donation is 500,000 Dilithium in Part 1. Warp needs barely change from part to part, so a ship that finishes Part 1 at warp 70 can finish the rest.
For the Part 4 choice, the Breen path is the clear pick unless you need Ship XP: it pays 300,000 Officer XP against 150 Ship XP on the Tholian side.
Are the Brimstone rewards worth it?
Yes, for a level 42 player. The chain pays 2 Worf shards, 13,420,000 Dilithium, 25,900,000 Tritanium, 30 each of 4★ Uncommon Refined Crystal, Gas and Ore, and 100 × 3 Hour Speed Up, plus either 300,000 Officer XP or 150 Ship XP from Part 4. The effort is seven named fights and one small Dilithium contribution. More chains are in the STFC mission guide.
