Minecraft Sky Thaumcraft Wands?

I recently started to play the somewhat older Minecraft Modpack "Sky" with a few friends. Now I started with Thaumcraft and I don't know how to recharge your wand, because the nodes with which you normally do the whole thing are nowhere to be found. So how can you recharge these walls or are there any nodes somewhere?

You can find nodes in the Twilight Forrest. You can also take these with you with Thaumcraft options.

In addition, in Thaumcraft 3, the sticks can be wonderfully charged on bully arms. Every mob killed drops the essence like exp bullets. Unpack the wand and it will recharge.
