The big obstacle facing the Department of Historical Research in compiling this report is that we have been able to find almost nothing about a herb called Black Lotus. There's certainly no record of a plant that fits the name growing wild in any part of the Empire, or being cultivated by Imperial citizens. There's also nothing reliable to point to the supposition that it grows in the vicinity of Night-aligned regio. There are certainly peculiar plants associated with regio of all stripes - such as realmsroot - but nothing that feels like it matches the intent of the historical research commission.
