All over Omnispace, portals were opening to the netherworlds. Creatures born in the fires of hell were pouring forth, attacking everything they saw. Some tried to defend their homes in vain, while others took whatever personal belongings they had and tried to escape.
Some managed to get off world in the few spelljammers they could find, but Colicor had ordered most Omniversal Defense Force ships junked for the Planar Gate construction. The few private ships that could be found were either in serious need of repair, understaffed and overcrowded, or lacking a helm or helmsman.
A few ships did manage to escape in time. A rag-tag fleet of ships, made up of a few junkers, some battered squid- and hammerships, tradesman and dragonfly ships, as well as an old cuttle command that was converted to a floating restaurant. The fleet gained a few more ships as it made its way to the spherewall. Other ships tried to escape, but the hellspawned attackers had destroyed them as they tried to leave the atmosphere.
All told, of the recorded ships in the fleet, 119 ships managed to escape. In contrast, at the peak of spelljamming travel, there were over ten million ships in all of Omnispace.
The planets of Omnispace didn't fare as well either. Tymar, an inert fire world and the closest to the sun Lora, was uninhabited. It's atmosphere long burned away, there was no evidence that anyone lived there. As the planar boundaries fell away, Tymar's core, a gateway to the planes of fire and air, opened. The planet's core ignited, as geysers of air began to push the planet out of its orbit. The small world was sent reeling out of control.
Maclear, the waterworld of the system, was invaded by hordes of hellspawn. Most of the natives were able to escape destructions because they could survive underwater, but the magical floating cities the sea- born Maclearians used to trade with other worlds were destroyed. Hordling invaders destroyed shops, goods and people on a destructive rampage. The magical devices that kept the cities afloat were corrupted by the planar intrusions: Each failed, and the cities sunk straight to the center of the planet, each becoming a watery tomb for the inhabitants.
Duranus, Omnispace's primary food supplier and home base for the Omniversal Defense Force took the worst of the attacks. Planar gates opened around the world at the same time, disrupting the world's gravity plane. Seismic activity was increased by the planar intrusions. With each new gate, a new quake rocked a part of the world, also weakening the planar boundary of Duranus. With each new quake, a new gate opened, causing a new gate. It finally became too much for the fragile world. About an hour after the first gate appeared, Duranus literally shook apart from stress. No one was able to escape the planet. Billions of souls were lost.
Gobul, the air world that was home to Omnispace's dragon population, was not immune to the invasion. Portals opened throughout the air world's multi-layered domain, tossing literally thousands of hordlings to their doom. The dragons, gem, chromatic and metallic, all recognized that there was no escape from the invaders, so they all launched a counter offensive. Powerful draconic sorcerers opened planar gates of their own, some bent on taking the fight directly to the hellspawn, others planning on joining the wars.
Something happened, however. Even the most brilliant of sages could not tell what happened. The dragons never made it to the outer planes. Many have theorized what happened. Some believe that the dragons simply 'blinked' out of existence, while others say they merely ended up on other worlds to continue their constant struggles. However, there are a handful of sages who believe that the dragons actually travelled through time as well as space, to a pure world where, through the actions of the god of the dragons, forgot their origins in Omnispace and lived their lives anew. Some believe that this is the origin of a legendary council of wyrms, but nothing definite has ever been proven.
