Rau hei glyphs indicate the beginning of a 'dark season', measured as 243 days long, for examples:
Rau hei means 'mimosa branch', and when Metoro said rau hei he presumably referred to the curious behaviour of the mimosa plant: '... In the evening the leaflets will fold together and the whole leaf droops downward. It then re-opens at sunrise ...'
The glyphs which come 'at sunrise' (243 days after a rau hei) can apparently always be characterized as indicating a 'rebirth' (of the type of 'light' which vanished 9 * 27 days earlier). |
