Hiergamenon Sorcery description spelling error, in the Techs_Amarian.xml file:

    <TechDef InternalName="Sorcery">
        <DisplayName>Sorcery</DisplayName>
        <Description>Dwelving deeper into the arcane arts allows you to cast new kinds of spells</Description>

Hiergamenon issue, there are 2 entries for Monument and one of them has a spelling error, I'm guessing it should be prestigious, again in the Techs_Amarian.xml file:

    <ImprovementType InternalName="Monument_ScenicView">
        <DisplayName>Monument</DisplayName>
        <Description>Monuments can be built on prestious locations.  They produce 1 Influence per Season.</Description>

The other Monument entry has a tag of <Provides> that I noticed in the xml says Askwake instead of Ashwake dragons, I'm not even sure if this is ever displayed anywhere but I thought I'd mention it anyway:

    <ImprovementType InternalName="Monument_TempleOfTheDragon">
        <DisplayName>Monument</DisplayName>
        <IgnoreDuplicateImpLimit>1</IgnoreDuplicateImpLimit>
        <RequiresCity>0</RequiresCity>
        <RequiresResource>1</RequiresResource>
        <SupportedResourceType>TempleOfTheDragon</SupportedResourceType>
        <PreferredTerrain>Category:Land</PreferredTerrain>
        <HideInHiergamenon>1</HideInHiergamenon>
        <LaborToBuild>88</LaborToBuild>
        <GameModifier>
            <ModType>Player</ModType>
            <Attribute>LimitedUnitCap</Attribute>
            <StrVal>AshwakeDragon</StrVal>
            <Value>3</Value>
            <Provides>Recruit 3 Askwake Dragons</Provides>
        </GameModifier>

Hiergamenon Tower of Dominion Description spelling mistake, missing an 'i', again from the Techs_Amarian.xml file:

<ImprovementType InternalName="TowerOfDominion">
        <DisplayName>Tower of Dominion</DisplayName>
        <Description>The Tower of Dominon reduces your Unrest by 10% and improves the city's Growth by 0.5.  A faction can only build one Tower of Dominion.</Description>

Hiergamenon Tower of the Magi description has resistance spelled with an 'e', again from the Techs_Amarian.xml file:

    <ImprovementType InternalName="TowerOfTheMagi">
        <DisplayName>Tower of the Magi</DisplayName>
        <Description>The Tower of the Magi increases the spell resistence of all units produced in this city by 10 and protects the city from the spells of enemy casters.</Description>

Hiergamenon Town description has agriculture missing the first 'r', again from the Techs_Amarian.xml file:

    <ImprovementType InternalName="TradeGuild">
        <DisplayName>Town</DisplayName>
        <Description>Devote this city to agiculture, financial and production pursuits.</Description>

I'll add more as I spot them.
