First of all, I like to express how much I love vintage story and how I very much enjoy the new content coming out.
During my playthroughs I kept thinking the temporal storm warnings were a bit un-immersive, so that got me thinking. What if instead of a text warning, the following would happen:
Instead of "a light/medium/heavy temporal storm is incoming", it starts to thunder in the distance, and the skybox changes to a more rusted tint.
Instead of "a light/medium/heavy temporal storm is imminent", the thunder is more frequent and with every lightningstrike the temporal stability drops a bit and the rusted filter is more intense for a second.
