Timeline update

I've totally lost track of how much time has passed in the D&D world, and keeping track is going to be important if you're in charge of a kingdom. So here we go:

Sypheros 20	The Battle of Stoneskull. Grim's army defeats Jalahand and Grim becomes warlord of the region. Burr is killed by a trap.
Sypheros 21	The party receives a letter saying that the Daughters of Sora Kell endorse Grim's rulership of the region. Grim and Zumm embark on a tour of the region, while Verschoyle and Zurga begin creating a flesh golem. During his tour, Grim spreads word of his new policies: taxes are reduced, but are to be delivered rather than collected, and anyone who wants to can go to Castle Granis to be tranied into Grim's army. Some chieftains object to this, thinking Grim was trying to steal away their best warriors, but Grim tells them where they can stick this objection. During the tour Grim also meets Hurgadar, a mongrelfolk barbarian, who agrees to accompany Grim in search of adventure.
Aryth [November] 20	Grim finishes his tour and arrives back at Stoneskull to pick up Verschoyle, who has finished his flesh golem.
Aryth 21	Grim, Zumm, Verschoyle and Zurga arrive back at Castle Granis. Some goblins attempt to assassinate Grim using warforged bane arrows. The plot turns out to be the work of a group of Tsochar, who were inhabiting the bodies of the cleric Merred Nastor and his goblin disciples.
Aryth 27	The party tracks the tsochar down in the tomb of Dragith Nurn, which the dreaded E.K. was using as a lair. They kill E.K. and encounter a group of bearded devils in the caves below, who are guarding a strange crystal set into the wall.
Vult [December] 7	The party is recruited into the Droaam army, a short stint of service to prove their loyalty to the Daughters of Sora Kell. They are also introduced to Paik, a changeling bard who is to travel with them.
Vult 14	The party march south from Graywall with the rest of the Daughers' army, under the command of Horde Commander Koll.
Zarantyr [January] 5	The first skirmish of the war. Grim and the rest of the party lead their goblin soldiers to defeat an enemy battle sorceror and destroy a siege engine. They then kill an enemy spy who was hiding in a nearby village. That evening, they repel an undead attack on the army, which is by this time besieging the enemy city. Horde Commander Koll presents Grim, Zumm, Verschoyle and Hurgadar with military decoration to recognize this.
Zarantyr 6	The party infiltrates the Temple of the Cleansing Blade and assassinates the enemy high priest. Victory swiftly follows for Horde Commander Koll's army.
Zarantyr 7	Grim, Verschoyle, Hurgadar, Zurga and Primrose explore the lower levels of the Temple of the Cleansing Blade.
Zarantyr 28	The party arrive back at Graywall with their army.
Olarune [February] 2	While the goblin army makes its own way back to Castle Granis, Verschoyle and the rest of the party attend a gathering of the Society of the Shadow Art, a regional wizards' circle. Verschoyle is accepted for membership. The party also meets Mavik Hilford, another wizard and new member of the Society. Verschoyle asks Vurdak 'Deathlord', a foul flesh-warper belonging to the Society, to upgrade Primrose with a magic longsword.
Olarune 9	End of the Society gathering. Mavik entreats the party's help to rescue his familiar from the clutches of Zilkloog the Mind Flayer. The party teleports back to Castle Granis and then goes to Zilkloog's village in the battle wagon
Olarune 17	First assult on Zilkloog's temple. The party defeat the guards but then the party breaks up when it transpires that Mavik had been asked to bring Zilkloog food in exchange for the return of his familiar. Grim and Hurgadar return to Castle Granis via battle-wagon. Verschoyle and Zurga teleport to Graywall to stay at Tharrad Katarn's house. Mavik, Zumm and Paik go their separate ways.
Therendor [March] 9	Vurdak 'Deathlord' visits Tharrad Katarn's house and brings with him the upgraded Primrose.
Therendor 15	Sir Ivan, Exorcist of the Silver Flame, and Horgar Horgar, bugbear fighter, arrive in Graywall looking for clues about the whereabouts of Zilkloog, whom they have been ordered to slay. After a brief stand-off with Tharrad Katarn they team up with Verschoyle.
Therendor 22	Ivan, Horgar, Verschoyle, Zurga and Primrose arrive at Castle Granis, where Grim agrees to help them slay Zilkloog.
Therendor 23	Verschoyle, Ivan, Horgar and Grim teleport to the Val'druusk Observatory in order to learn more about Zilkloog's lair by scrying on him. They learn that he has replaced his temple guards with gnoll mercenaries. The party also find Zumm, who appears to be in some form of suspended animation, next to the scrying orb at the observatory. They then checked on the tribe of grimlocks which they had nearly wiped out and were now protecting. The grimlocks said that they did not have a viable population, and would appreciate news of another grimlock tribe they could unite with. The party teleport back to Castle Granis and the leave on battle wagon for Zilkloog's temple.
Therendor 30	Ivan, Horgar, Verschoyle, Grim, Hurgadar and Primrose arrive at Zilkloog's temple. They defeat the mind flayer (who turns out to be a tiny runt mind flayer, the giant mind flayer having been an illusion), and Ivan burns its head in front of the village.
Eyre [April] 7	The party arrive back at Castle Granis.
Dravago [May] 1	(The next meeting of the Society of the Shadow Art is sheduled for this date.)

Phew! All those times I've said "A few weeks later..." really do add up!
