Needless to say, the herb garden of a Thearch was extremely valuable.
Although many precious herbs had been kept away before they became immortal, the normal herbs that were left behind became precious too after growing for thousands of years.
Most of them could not last that long, but they could provide nutrients for the soil after they withered.
The subsequent seeds that germinated in this soil could get much better nutrients for their growth and could become supreme-grade herbs and sometimes even Sage-grade.
Also, most of the Thearches would not keep away all the Sage herbs in the garden before they became immortals.
Some herbs were not good enough to boost their power anymore and would be left behind for others as fortuitous opportunities.
After being there for over 10,000 years, these herbs had become extremely useful and powerful now.
