Still plant based like RW, if the Green Age hint above isn't enough, the Cult Compendium goes on to state -

the Twins helped spare the living forests, the
Aldryami considered the burning of firebone (coal)
and earthblood (oil) to be desecration of their dead.
And though Aldrya shares the Twins’ love of
Fertility, her enmity for them is little less than for
Oakfed himself.
