Solar Ash takes place in a breathtaking open world that the main character, Rei, must explore in order to save her home planet. Along the way, Rei can discover Voidrunner caches, logs from the members of her Voidrunner team that chronicles their attempts to save their planet from the black hole known as the Ultravoid.
The Eternal Garden is one of the most striking environments in Solar Ash, filled with glowing fungi and atmospheric lighting. It also has five different Voidrunner caches for Rei to find, left behind by Pyat, one of the more zealous and eccentric members of Rei's crew. Finding all six of Pyat's caches rewards Rei with his suit, which heals her after defeating an enemy.
5 Unlock The Tower Door
After activating Cyd's platform directly in front of the large, dilapidated cathedral, players should turn back to the entrance and look the left to see a pillar of clouds with a building at the top. A Voidrunner cache can be found inside this building, but it's blocked by a sealed door that can only be unlocked using color-coded mushrooms spores.
Whack the yellow bulb in front of the cathedral to collect these spores on Rei's body, then quickly dash across the clouds to the tower. The small yellow protrusion to the right of the door will take the spores from Rei and open the door, giving her access to the Voidrunner cache.
4 Atop The Rib
If players look to the right when facing the pathway into the cathedral, they'll see what appears to be the ribcage of a giant, decomposed beast. At the top of the closest rib sits another Voidrunner cache, along with several flying remnants.
Skate over to the base of the rib, deal with the nearby Remnants, then climb the black goo up to the second level. The Voidrunner mark can be seen on the side of the rib here, and there's more black goo to climb on the back of the rib itself. Climb to the top while taking out the flying Remnants to claim the next Voidrunner cache.
3 Over The Vertebrae
To reach this Voidrunner cache, skate to the right of the cathedral entrance toward the giant ribcage. Pass the two Remnants that charge toward Rei if they spot her, and skate over to the black goo below the toppled over cathedral tower. Climb up and skate through the cathedral tower to find a tall, glowing mushroom at the top with the Voidrunner mark on it.
Boost off the cliff and onto the giant vertebra below, then grapple across the large gap using the two suspended grapple points. Boost off the next two vertebra and use a well-timed double jump to reach the roof of the nearby building. Another Voidrunner cache, as well as Pyat himself in an unresponsive, suspended state, can be found here.
2 Past The Thorns
Head left while facing the cathedral entrance and skate along the clouds, until coming upon another spit of land close to the base of the cathedral. Ahead, the player should see a pair of flying remnants over a series of small islands with plasma balls on them. A Voidrunner mark can be spotted on the side of the first island.
Hop over these islands, taking care not to fall onto the spiky thorns below, and grapple to the ridge that runs around the edge of the cathedral. Take out the smaller Remnants waiting up ahead, and round the corner to find the next Voidrunner cache waiting at the end of the ridge.
1 In The Underground Chamber
The final Voidrunner cache can be found below the crumbling, desolate cathedral. There's a pit inside the cathedral itself, but it's sealed behind a door that requires all three mushroom spore colors to unlock. Once the pit is open, drop down inside and being navigating through the darkness.
Strike the glowing mushrooms to make it easier to see, while moving through the caverns to unseal all the doors leading the final chamber. Once inside, jump onto the rocks to the right, boost across the gap to the cliff on the other side of the chamber, and claim the Voidrunner cache nestled in the shadows there.
