Moltenchannels in a nutshell, Part 1: A recap of our first 10 years*:
(Note: This is entirely in my own words, and does not reflect the intentions of people during their turns necessarily.)
Year 1: "What a nice peaceful place. Let's turn it into the hellish bloodstained seal keeping in an interdimensionally-imprisoned dwarf from Ardentdikes. This can hardly go wrong at all." (Massively paraphrased). Walls set up, beginning of magmaworks..um....begun.
Year 2: The new overseer expands the fledgling fortress, accidentally incinerates his wife, and robs our first caravan.
Year 3: A terrifying figure of death, AKA our head nurse, takes over, builds a hospital (later to become the first of our many Hospitals of Death). Magma moat is dug, first diplomat hideously maimed.
Year 4: Siege repelled by Urist Mcbadass, Sealspines the Skewered Basis of Beards (Best. Name. Ever.). Undead arrive. Undead kill Urist Mcbadass, Sealspines the Skewered Basis of Beards. Undead repelled. More undead arrive. Massive siege arrives. Goblins and undead fight. Undead win. Goblin army rises from the dead as more undead. Another siege arrives, massively reduces undead and drives away necromancers. First FB. Final goblin seige arrives, wipes out undead, surrounds fortress.
Year 5: Military formed and organised. First mass grave dug. Totally Safe and Not at All Dangerous waterfall system established for our tiny main dining hall. I get dorfed for the first time. More FBs arrive. Food stockpiles re-established after being devastated by the previous few years. Moat fixed so that it actually stopped enemies. Main storage areas set up and organised.
Year 6: Tower, giant tomb, massive farms set up. Overseer goes insane due to technical problems.
Year 7: Corpse disposal railway built in pragmatic attempt to clear the mountains of dead things. Adamantine discovered. Moat modified, first reactor built, first of many, many, many forest fires.
Year 8: DuckThatQuacks (original creator of our Big Bad, Urist McDuck) takes over. Builds sniper tower with no floors. Allows McDuck to escape Ardentdikes and start heading for us (very slowly, apparently). Sets up (via his dorf, McDonald) McUrist's Family Restaurants, appoints himself Baron. Forgotten beast smashes through our wonderfully insecure cavern compound and wipes out recruits. I discover I got myself killed by a vampire a while back.
Year 9: First massive set of updates by CaptainArchmage. Reactor finished and activated. Our infamous physics oddities mean the standard designs don't work and need modifications. Lots of cleaning up. More stuff probably happened, but it'd take all day for me to read this stuff (I'll edit it in later). Shroud of Armok (our main magma weapon) constructed. Probably causes a forest fire as well.
Year 10: More mass graves. At this point we're apparently surrounded by zombies. Again. Military is revamped again into new squads, some of which last a full 10 years. 5 necromancers turn up. Siege weapons set up. First *deliberate* forest fire.
The first decade ends with most zombies dead, the necromancers gone, and everyone more or less happy. Suffice to say, this did not last.
*I was going to do all 20.5 years, but It was taking For. Freaking. Ever. I'll do the rest later.
