This spell is a part of the Influence spell chain and found in the Influence rune stone.
I first knew I was dreaming when I went to speak, and behold no sound came rushing out. It is a common occurrence, whether it be in a pleasant dream or a terrifying nightmare, that the dreamer cannot speak nor produce any sound. It is like the space within their dream is silent. Space, in its truest sense, is silent. The vast emptiness between things carries nothing - no sound, no signal, no noise of any kind. This is the nature of space that the mentimancer understands most intimately, the inner silence that Dream has always known how to find and how to extend.
Silence of Space reaches through Dream and imposes that fundamental quiet on the area surrounding the caster, not blocking sound so much as convincing the space itself that sound is not something that happens here. Within the radius nothing makes noise. No footstep, no clash of weapons, no voice. Those inside the silence can move and act with complete acoustic invisibility, undetectable by sound though still visible to any eye that looks their direction. Spells can still be cast for runic elements do not require sound to work, but no verbal component, no warning cry, no called order can pass through the boundary in either direction. What is outside cannot be heard inside. What is inside cannot be heard outside. The silence is total, and it belongs to whoever stands at its center, as if they were standing within a dream space itself.
