Siege of Somonor - Eldar War Host Strikes: So it was that when Eldorath Starbane led his advance force to the chill caldera that concealed the tomb's entrance, he found it held against him. Confident of victory, the Farseer launched his attack without waiting for the rest of the host -- it was a mistake that would cost the Eldar dearly. For every advance the Eldar made, Imotekh had prepared a counter. Nowhere was this more clearly seen than when a Wave Serpent and its Vyper squadron escort split off from the main Eldar assault and drove hard towards the battle's heart, their goal to assail Imotekh directly. Yet Imotekh had expected such a move; indeed, he had left certain sectors of his defence enticingly weak to provoke such an attempt. So it was that as the Vypers closed into killing range, there was a blinding flash of emerald light, and the immovable bulk of a Monolith materialised between the Eldar and their prey. Unable to pull up in time, the lead Vyper slammed full-tilt into the slab-sided Necron war vessel, the resulting fireball leaving not so much as a scorch mark on the Monolith's living metal hull. Saved by a split-second's warning and their pilots' preternatural reflexes, the other Vypers broke formation and banked hard, swarming about the Monolith's flanks like angry insects as they brought their weapons to bear on the new target. Yet the damage had already been done, and with the Vyper screen disrupted, the Monolith was free to bring its Particle Whip to bear on the Wave Serpent behind. This it did with pinpoint accuracy, the first blast reducing the grav-tank to a shattered hulk, and the second obliterating the handful of Aspect Warriors who crawled from the burning wreckage.At every turn, Imotekh sought to deny the Eldar their most important tactical advantage -- manoeuvrability. Deathmarks sniped Jetbikers from their saddles. Flotillas of Heavy Destroyers positioned about the rim of the caldera targeted Falcons and Fire Prisms with volley after volley of crackling Gauss Weapon fire, punching through hulls and disabling anti-gravity units. By the time Starbane realised the severity of the threat he faced, his force was incapable of retreat and had no choice but to press on. Yet Imotekh's methodical countermeasures could only hold back the Eldar for so long. For every crippled Necron that reassembled itself and rejoined the firing line, another succumbed to critical damage and was whisked away by retrieval teleporters. Little by little, the Stormlord's forces wore thin. The Monolith was destroyed in a bold assault by Fire Dragon Aspect Warriors, the Deathmarks eliminated by Pathfinders, and the Destroyers were scoured from their perch by Dark Reapers. And still the Eldar came -- the main body of the host had arrived and were massing for a second attack. Imotekh knew that his remaining forces could not hold against this new wave of attackers -- but then, it had never been the plan to do so. Summoning angry storm clouds to cover his retreat, Imotekh unsealed the great stone entrance and led his dwindling army into the darkness of the tomb. Had Starbane been less arrogant, less certain of his superiority and that of his race, he might have recognised the trap for what it was and withdrawn. Yet the Farseer cast his runes in haste and saw only victory ahead, and so missed subtle warnings hidden amongst the skeins of fate and the flow of the Empyrean.Long did the Eldar walk in darkness, through dusty vaults and chambers that had not been seen by the living for millions of Terran years. Though they caught sight of many technological wonders, the intruders caught not so much as a glimpse of the Necrons they pursued, nor the tomb's robotic servitors. The deeper Starbane progressed into the tomb without any contact, the more he grew convinced that the enemy had simply fled, escaping into the subterranean labyrinth in order to fight another day. Deeper and deeper into the tomb the Eldar went until, in a colossal vaulted chamber many miles beneath the surface, Imotekh sprang his trap. Without warning, quantum gravitic force fields flickered into life at the chamber's exits, sealing the Eldar within.
