The absorption of the distant echoes didn't get any less tortuous and painful in the following days but brought unexpected, positive results.
Khan still stuck to the lightest echoes, alternating their absorption with short naps to disperse the headaches and mental fatigue the process created. Those memories were mostly useless, and the Great Old One's absence of thoughts in them seemed to agree with that evaluation, but Khan occasionally obtained something valuable.
The lightest memories contained information and sensations the Great Old One took for granted and didn't bother studying. Most involved the weather, Coravis' sea's movement, the air's taste, or the vague connection to a wave of pale green mana.
However, some involved the ancient creature's movements. The snake didn't need to think when slithering or using its gargantuan body for menial purposes, but the experience was priceless for Khan.
