Once every two hours, a group of Skyguard will launch an attack from the Sha'tari Skyguard base at Ogri'la to Bash'ir Landing. The remaining time for the attack can be determined by talking to the Aether-tech NPC at the landing pad in the quest 
[20-30] Assault on Bash'ir Landing!. Once the attack is underway, several Skyguard NPCs will engage the mobs at Bash'ir landing, and a series of NPC vendors will appear. The items provided by the vendors increase in quality as the attack is maintained, until eventually the entire area is wiped out by a large number of elite attackers.
Stage 1[]
Assault begins:
- Bash'ir Arcanist yells: Get over there and realign The Crystal Forge.
- Skyguard Aether-Tech yells: A discovery! I need aid with these measurements... I'll send a signal to my colleague!
Stage 1 complete:
- Aether-tech Assistant yells: This forge can make unstable concoctions... to study them, I need Apexis Shards!
After the skyguard land a Slavering Slave will move in to attack the NPCs at regular intervals for a minute or two. The Aether-tech Assistant appears after defeating the elite Bash'ir Flesh Fiend. A group of about 5 is recommended for this phase.

These flasks only work in Blade's Edge and Gruul's Lair. Like all flasks they last 2 hours (Changed to 1 hour in Patch 3.1.0) and the effects persist through death.
Stage 2[]
Stage 2 begins:
- Skyguard Aether-Tech yells: The disruptor towers over charged the crystalforge, and uncovered more secrets! Hold them! Hold them while we gather new data!
Stage 2 complete:
- Aether-tech Adept yells: I am growing amazing crystals from these waters. For catalysts, I must have more Apexis shards!
Bash'ir Subprimals crowd the area. Once enough have been dealt with, 3 Elite Disruptor Towers appear. Destroy them, and the Aether-tech Adept appears. The disruptor towers launch AoEs at the NPCs and players; a large group (raid of 25) is recommended to clear this one, but it may be possible to get the gems with a smaller group, if you buy quickly and then wipe. It has been completed at level 70 with as little as 3 people (Rogue, Tank Druid and Holy Priest), however, this amount is not recommended.

Stage 3[]
Stage 3 begins:
- The Grand Collector yells: They called me down from K'aresh to deal with this band of misfits? Unbelievable! Prepare to be collected!
Fighting The Grand Collector:
- The Grand Collector yells: Enough! I will take care of these fools myself!
Stage 3 complete:
- Skyguard Aether-Tech yells: At last! The information we seek! Gather quickly, skyguard. We must soon return to headquarters with our findings!
- Aether-tech Master yells: Its properties are amazing! Provide me with Apexis crystals, and I'll form weapons and armor within crystal geodes.
Event ending:
- Skyguard Aether-Tech yells: Our studies are complete! Well fought! Headquarters will pour over our gained measurements and, with luck, uncover the Bash'ir's intentions. Now, to the skies!
The final wave of Bash'ir Reckoners and Bash'ir Controllers appears shortly after the siege towers have been destroyed and contains a powerful boss mob called The Grand Collector that splits into three at some point during the fight and has some very nasty AoE spells. The Aether-tech Master appears upon completion of the event. The Master sells Meta Gems, Geodes and Accelerator Modules:

The Metamorphosis Geodes can be "opened" like lockboxes and most likely contain a rare armor piece.
Accelerator Modules[]
These can be used on the small rods that stick up from the ground near the long tunnels of rings on Bash'ir Landing. These are rather buggy at the moment, so be sure that no mobs are in the tunnel, or about to enter the tunnel when you use the controls or the summoned boss could bug and despawn. Summoned harbingers drop an [Apexis Crystal] and a couple of boe items, easily five-mannable. Watch out for their spell reflect though.
