Gyllber is a Caelian member of the Titan Dockworkers Union, serving as the station's master shipbreaker and director of deep space salvage operations. In essence, Gyllber is the person who grants salvage companies licenses to operate as extensions of their own authority and, importantly, allows them to dock their cool spaceships inside the Garden dome itself instead of docking out in Old Titan Station. Gyllber is a jovial fellow, they love a good joke and will frequently try to work their own best attempts at one into a conversation- laughter is good for the jellies, after all! Despite this fun and friendly demeanor it is surprisingly difficult to actually get a salvage license out of them, even if your paperwork is correct and in order. With so many ships flying out of so many worlds its more important than ever to keep space free of hand-made debris; salvage work can be fun and adventurous but it's a very dangerous job, so if Gyllber doesn't think you got the jellies for it they're going to save someone else the trouble of scooping up your own eventual shipwreck.
There are generally three fates for every starship in the Sol system: they end up in the used ship market, they end up a space wreck or they end up in the master shipbreaker's drydock. When a ship survives to the end of its service life and is decommissioned it gets carefully deconstructed, broken cleanly down into its component parts and distributed to be recycled into many other things. While shipwreck salvaging is often a rough and tattered job in deep space, Gyllber's work is very clean and precise, done in brightly-lit gravity-controlled hangars with the aim of saving as much of the decommissioned ship as possible. Gyllber directs a team at their drydock but they like to tackle the job themselves as well, wielding an 2XL Breach Cutter like a surgeon's scalpel. A ship ending up under this cut is generally considered the best possible ending, as it is indicative of a long and fruitful service life and a transition into something new.
Gyllber and Lamp are close friends and are informally regarded as the alpha and omega of Titan's starship industry. Lamp will usually keep a shortlist of useful things she needs for her new starship builds and Gyllber will be sure to procure them from their decommissioning work- in fact, a lot of the raw material Gyllber recovers gets recycled into the hulls of Lamp's ship designs. It's a great circle of life, preventing Titan Garden from producing an excess of material waste in an environment where resources can be pretty scarce if they're not carefully managed. The two Outer Belt denizens will often spend time together when they're not on the clock, enjoying a drink at a café and sharing stories with each other. It's a good vibe all around.
While Gyllber's salvage licensing rules can be fairly cryptic, renewing those licenses is relatively straightforward. There is some small amount of documentation review, to check that you've been actually working over the past year, but ultimately their license renewal process boils down to a day at the drydocks. Gyllber asks that the captains of Titan's salvage companies spend a day doing the grunt work of decommissioning a ship- they want to be sure that no captain is a sideline director, that they themselves can perform the duties of a shipbreaker safely and effectively. It's not glamorous work but it is critically important to keep metal debris out of collision course with other ships- saving lives, preventing more debris from accumulating and just overall being good custodians of the shared space of the Sol system- so if a captain isn't able or willing to do the work themselves there's plenty other crews looking to procure a license and do the job instead. Bryce hates renewal day, he got the Ermine specifically for that big arm and laser cutter so he didn't have to bend down and do all his breach cutting by hand. Amy, on the other hand, loves renewal day. For her it's a fun day to go out and solve a really big puzzle with her machinepilled devilbrain. Bryce swears he applied for his license on a different day than Amy, but the two are always called in for renewal at the same time. The truth is, Gyllber fudges their renewal schedules on purpose. The two captains do professional work, but sticking them together and watching them squabble, well, that's just really good for the jellies.
